Pat ted Ans- 5. 1 1a Application filed May 9, 1919. Serial No. 295,978.

To all whom stenc l concern:

Be it known that we, (1) Josnrn SULWEB- SKI and 2): GorTLInn Rnson,citizens of Poland, having declared our intention to become citizens ofthe United States of America, residing at Decatur, in the county ofMacon and State of Illinois, have invented certain new and usefulImprovements in Boilers, of which the following is. a specification.

The primary object of the present invention is to provide a boilerespecially adapted for use in the washing of clothes and similararticles in which there is provided a false bottom in the boilerreceptacle that is under spring tension in its lower operative position,and which is adapted to be elevated to a convenient point when it isdesired to remove the contents; of the boiler therefrom.

With the above general objects in view, the invention consists in thenovel form, combination and arrangement ofparts hereinafter more fullydescribed and shown in the accompanying drawings, in which likereference characters indicate similar parts through the several views.

In the drawings,

Figure 1 is a side elevational view of a closed boiler constructed inaccordance with the present invention with a portion of the side wallthereof broken away, showing the false bottom of the boiler in itslowered operative position,

Fig. 2 is a top plan view thereof with the cover removed,

Fig. 8 is a cross sectional view of the boiler proper with the falsebottom shown in end elevation and in its lowered position,

Fig. 1 is a crosssectional view similar to Fig. 3 with the operatingsprings for the false bottom expanded and with the false bottom inelevated position,

Fig. 5 is a detailed sectional view of a portion of the boiler showingthe latch arm for holding the false bottom in its lowered position,

Fig. 6 is a detailed sectional view similar to Fig. 5 with the latchmechanism shifted to permit the elevating springs of the false bottom toassume their expanded position and with the false bottom elevated, and

Fig. 7 is a top plan view of a portion of the boiler showing the sidechannel for containing the retaining latch.

Describing the invention more in detail, the reference numeral 8designates a boiler especially adapted for cleaning clothes having thehandles 9 for transporting the same and the outletfaucet 10 at. thebottom side thereof, there being provided an ordinary form of cover 11for confining the steam therein.

A false bottom 12 of the samev contour as the boiler is arranged thereinand is provided with a plurality of openings 13, to permit freecirculation of water and Steam in the-boiler. The lower face of thefalse bottom 12 is provided with a plurality of depending annularsockets 14L that are so. arranged-as to be in alinement with upstandingstuds 15 carried by the bottom wall of the boiler 8 while expansioncoiled springs 16 have their lower ends received upon studs 15 with theupper ends thereof positioned in the sockets 14. i

A. latch mechanism is provided to hold the false bottom 12 in thelowered position shown in Figs. 3 and 5 and includes a latch arm 17pivoted upon the horizontal arm 18 arran e'edacross the compartment 19formed inwardly of the side walls of the boiler 8 by the semi-circularwall 20, thefalse bottom 12 accommodating itself to said curved wallsbybeing cut away as at 21 to lie adjacent tosaid curved walls throughoutits length, as more clearly shown in Fig. 7. The lower end of the latchrod 17 is provided with a hook 22 adapted to be projected through anopening 23 formed on the adjacent lower end of the wall 20 and inprojecting position inwardly of the wall 20 is adapted to bereceivedbetween the lugs 24 carried by the false bottom 12 to hold thefalse bottom in its lowered position as shown in Fig. 5 against thetension of the springs 16. The

latch rod 17 adjacent the upper end thereof is provided with an inwardlyprojecting pin 25 adapted to be extended through the opening 26 providedadjacent the upper end of the wall 20 and in projected position as shownin Fig. 6 is adapted to engage the upper surface of the lug 24: upon thefalse bottom 12 to limit the upward movement of said false bottom and toarrest the exerting force of the springs 16, the latch rods 17 beingoperated from the upwardly projecting end 27 thereof. It is to beunderstood that a plurality of sockets 14 and cooperating studs 15 withthe associated springs 16 are provided in any number desired, andfurther that it is preferably desired to provide the latch retainingmechanism for the false bottom 12 at opposite sides of the boiler 8 asshown more clearly in Fig. 2.

It is thought that the construction and operation of the device will bereadily apparent from the above detailed description, it being notedthat when the false bottom is in the position shown in Figs. 3 and 5,the hook 22 upon the lower end of the latch rod 17 is projected throughthe opening 23 for engagement with the lugs 24 to retain the falsebottom lowered against the tension of the springs 16. If the contents ofthe boiler has been boiled and steamed for a sufficient amount of time,the upper end 27 of the latch rod is engaged by the hand of theattendant and moved inwardly, thereby to release the hooked end 22 fromthe lugs 24 and to project the pin 25 through the opening 26 into theinterior of the boiler to engage the upper surface of the falsebottom 10upon an upward movement thereof caused by an expansion of the springs16; In the latter position, the contents of the boiler are moved to apointradjacent the upper end thereof and the water contained therein ispermitted to drain therefrom and percolate through the openings in thefalse bottom.

While the form of the invention herein shown and described is what isbelieved to be the preferred embodiment thereof, it is 'nevertheless tobe understood that minor changes may be made therein without departingfrom the spirit and scope of the invention as claimed.

What we claim as new is 1. A boiler comprising a receptacle having aperforated false bottom arranged Copies of this patent may be obtainedfor for selective engagement with said false bottom to retain the samein lowered position and to limit the upward movement thereof.

2. A boiler comprising a receptacle having a perforated false bottomarranged therein, depending sockets carried by said false bottom,upstanding studs carried by the bottom of said boiler, expansion coilsprings cooperating with said depending sockets and studs, a curved wallextending inwardly of the side wall of the boiler forming a compartment,a latch rod pivoted in said compartment, a pin carried by said latch rodabove and below said rod pivot, openings in said compartment wallthrough which the pins are adapted to be projected for selectiveengagement with said false bottom, to retain the same in loweredposition and to limit the upward tensioned movement thereof, the upperend of the latch rod projecting above the upper edge of said boiler toconstitute an operating handle.

3. A boiler comprising a receptacle, a false bottom arranged therein,expansion springs arranged between the bottom of the boiler and saidfalse bottom normally to force the false bottom upwardly, and a latchrod pivoted in said boiler adapted to engage said false bottom to holdthe same in lowered position and to limit the upward movement thereof.

4. A boiler comprising a receptacle, a false bottom arranged therein,expansion springs arranged between the bottom of the boiler and saidfalse bottom normally to force the false bottom upwardly, and a latchrod pivoted in said boiler having means to engage said false bottom tohold the same in lowered position and to limit the upward movementthereof, said means including a hook at the lower end of said rod and aprojecting pin intermediate its pivot point and its upper end.

In testimony whereof we affix our signatures.
